Actually, I think this can actually be adjusted to just re-use the
stack allocation, since rxkad_verify_packet() finishes one before
doing another in rxkad_verify_packet_1():

That looks very nice, yes. The same thing is needed in
rxkad_secure_packet(), right?

Yup. 4 leaf functions and the 2 callers.
